Central hub for school sites

I am sure this has been discussed around here, but I am a bit lost and well, that is the point. My school is a small high school community (120 students, 11 staff). We are using wikis for staff communication as well as to host online classes. Now we have about 7 different wikis, plus the district database, an alternative program database, email, texting, and the various other resources we like to use. Almost all of our students use Myspace and staff often uses that as a way to connect with students outside school.
I am considering creating a school Ning to try and consolidate some of this chaos into one central hub where we can link to online classes, discuss, question, post news and events, that sort of thing. I have used Moodle and find it to be way too confusing to navigate, plus I think utilizing student's knowledge of Myspace will help a lot. Staff are getting discouraged with too many resources to check and learn to use. i would like to streamline things.
Does anyone have suggestions for other ways to create a hub? Or is anyone using Ning this way? I would love to hear any feedback you all have! Thanks!
